Results of model selection using Akaike's information criterion (AIC) for the relationship between secondary production of <i>Dentinephtys glabra</i> and environmental factors.

Only the top five models with Akaike weight (wi) and R2 values are shown. Regression coefficients were expressed as Z values (estimate/SE). Factors are abbreviated as Cond (conductivity), Cross (cross-sectional area), Slope (bank slope), Water (Water content), Chl a (Chl a concentration), Temp (temperature), Clay (clay-silt content).
